MACHINE FOR PACKING STARCH.

SPECIFICATION forming part of Letters Patent No. 354,634, dated December21, 1886. Application filed August 3, 1886. Serial No. $9,868. (Nomodel.)

.To all whom it may concern.-

Be it known that I, PAUL H. GRIMM, of Glen Cove, in the county of Queensand State of New York, have invented a new and useful Improvement inMachines for Packing Starch and other Substances in Barrels or Packages,of which the following is a specification.

My invention is applicable to machines for packing various pulverized,granulated, or finely-divided substances, but is more particularlyintended for packing ground or pulverized starch, or starchin acrystallized state.

The invention relates to a machine which comprises avertically-movableplatform on which the barrel or package is placed, andmechanism whereby a jumping or jolting motion is imparted to theplatform and the barrel supported thereon during the operation ofpacking or filling the barrel, whereby the substance delivered into thebarrel will be condensed, or have its particles moved among themselves,so as to enable a greater quantity to be packed within the barrel orpackage than would otherwise be possible. In its preferred form themachine or apparatus comprises a stationary base-piece or bed,which hasa downwardly-extending central guide and a movable platform arrangedupon the bed and supported by a vertical stem which is guided within theguide of the bed. The platform has preferably-upon its top surface aprojection to fit the chine and head of the barrel,

and a shaft provided with a cam is employed for raising the movableplatform through its vertical stem or support, and then suddenlydropping it and allowing it to fall upon the bed or base-piece. By therotation of the shaft provided with a cam a rapid jumping, bouncing, orjolting motion is imparted to the platform and the barrel or packagesupported thereon, and by such motion the starch or other substance issolidly packed, or has its particles so moved among themselves as topermit of the greatest possible quantity being packed within the barrelor package. I also employ a shaft,which is arranged immediately belowthe stationary bed,and has upon it cams which workthrough slots in thebed, and by turning this shaft the platform may be raised out of rangeof the cam whereby the jolting motion is imparted to it, and will remainsta tionary while the barrel is headed and removed from the platform andan empty barrel placed in position thereon. Above the movable platformis a feeding-hopper having a spout which extends downward, and in thisspout are arranged a crank-shaft and a vibrating rod, to which thecrank-shaft imparts motion, and which, by its to-and-fro movements inthe starch or other substance in the feeding-outlet prevents the.substance from of the hopper, clogging therei In the accompanyingdrawings, Figures 1 and 2 aresectional elevations, in planes transverseto each other, of an apparatus embodying my invention; and Fig. 3 is aplan of the same, a portion of the movable platform being broken away inorder to shown the slotted .dowhwardly extending guide or trunk, A.

This guide Ais, as here represented, arranged centrally of the bed, andis circular in its transverse section. The bed A may be secured to thefloor or floor-beams by bolts or other suitable means.

G designates a movable platform, which is arranged above the bed A, andwhich may be of substantially the same size as the bed. This platformpreferably has a projecting portion,

0, upon its upper surface of suchsize and profile as to approximatelyfit the head and chine of a barrel, D, which is arranged thereon. Themovable platform 0 also has .a downwardly-extending stem or support, 0,which is here represented as formed integral with the platform bycasting, and which is fitted to the guide A, so as to be properly guidedthereby in its rising and falling movements.

Arranged below the parts of the apparatus described is a shaft, E, towhich rotary motion may be imparted by a belt running upon a pulley, E,and which has upon it a eam,-e, or other suitable projection, forraising the stem or support 0' and the movable platform 0. As

here represented, the stem orsupport C has at' its lower end a pivotedroller, upon which the cam e bears, and which prevents wear of the stemor support by the cam to such an extent as would reduce the length ofvertical movement imparted by the cam to the stem or support 0 and tothe movable platform 0.

It will be understood that when a rotary motion is imparted to the shaftE the cam 0 will act upon the roller 6 to lift the stem or support andmovable platform 0 0 once during each revolution, and if the cam e be ofproper profile, as shown in Fig. 2, it will, after raising the platform0 to the full limit of its movement, drop the platform suddenly andallow it to fall upon the bed A, thereby imparting a' sudden shock tothe contents of the barrel D. j

' If desired, a packing, d, of india-rubber or other suitable material,may beintroduced between the bed A and the movable platform 0,

as shown in Figs. 1 and 2, in order to reduce the blow which theplatform exerts in falling upon the bed A.

When a barrel has been filled and it is desired to head and remove itfrom the movable platform, it is very advantageous to have the jumpingmotion of the platform stopped in a convenient and ready manner. Toeffect this result I employ a shaft, F, which extends across and beneaththe bed A, and which has upon it cams f,working through slots f in thebed A. This shaft F may be journaled in bearings f at the sides of theupright guide 5 A, and it may extend through slots 0 in thevertically-movable stem or support 0', so as to not interfere with therising and falling movements of the platform 0. The shaft F may beoperated by the handle F.

As shown by dotted lines in Fig. 2, the cams f are represented as madein the form of simple eccentrics secured to the shaft F. Consequentlywhen the handle F is turned down to the position shown in Fig. 2 thecams f will be shielded by the bed A, and will be out of reach of theplatform C. When, however, the handle F is turned to a nearly-oppositeposition, the greatest projections of the cams f will be brought to theupper side of the shaft F, and by acting upon the platform 0 will raisesaid platform, so that the lower end of the stem of support 0 will belifted out of range of the cam e. The means described for lifting theplatform and its stem or support out of range of the cam e aredesirable, because then the shaft E maybe rotated continuously by power,and the jumping or jolting motion of the platform C may be discontinuedwhen desirable to head a full barrel.

The floor B may be slightly notched or grooved to permit the handle F tobe swung downward into nearly horizontal position; or the bed orbase-piece A may be raised slightly above the floor, if desired.

I have here represented a hopper, G, provided with a feeding-spout, G,as arranged above the platform 0, and in this feedingspout G is a valve,71, which, by means of a lever, k, may be moved to control the deliveryof starch or other substance from the hopper downward into the barrel D.In packing starch or other finely-divided substance there is a liabilityof its clogging in the feeding-spout G from the hopper G, and I havehere repre sented a rod or bar, t, as arranged in the out let from thehopper G, and to which motion is imparted by a crank-shaft, I, extendingtrans versely across the delivery-spout G. The bar or rodz'projectsthrough a bridge-piece or crossbar, t",at the outlet from the hopper,and when the shaft I is rotated a to-and-fro vibrating motion isimparted to the rod or bar 1', which tends to loosen the substance inthe delivery-outlet from the hopper and prevent its clogging therein.The shaft I may be operated by a chain belt or other connections, i,from ashaft, j, which in turn receives motion by a chain belt or otherconnection, j, from the shaft E. The wheel i on the shaft j, and bywhich the chain or connection 6 is driven, may be operated through themedium of a clutch, i, con trolled by a lever, i By means of this clutchthe shaft I may be rotated whenever desired to operate the rod or bar tand prevent clogging of the substance in the hopper-outlet; or saidparts may be left stationary and inoperative if there is no tendency ofthe starch or other substance to clog in the hopper-outlet.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with a vertically-movable platform to receive abarrel or package, and having a downwardly-projecting stem or support,of a guide for said stem or support, a shaft provided with a cam,whereby a j umping or jolting motion is imparted to the platform, andmeans, substantially as described,

for raising the platform and its stem or support out of range of saidcam, substantially as herein set forth.

. 2. The combination,withaplatform mounted upon a vertically-movablestem or support, of a shaft providedwith a cam for imparting a jumpingor j olting motion to the platform, and a shaft and cams below theplatform, whereby it may be raised out of range of the cam for jumpingor joltingit, so as to remain station- ICO ary while a barrel is headed,substantially as herein described.

3. The combination, with a base or bed having a downwardly-extendingguide, of a platform mounted upon a stem or support fitting said guide,and a shaft provided with a cam for imparting a jumping or joltingmotion to the platform through said stem or support, substantially asherein described.
